[edit] Brewing with acidulated malt

[edit] General brewing information

Acidulated malt was traditionally used to adjust mash pH in cities with extremely alkaline water. However, the lactic acid used also contributes its own distinctive flavor to the beer when used in significant amounts. Over about 10% of the mash, it becomes more difficult to work with.

[edit] Beer styles

Acidulated malt can be used to add a slight sourness to sour beer styles such as Berliner Weisse or Kentucky Common.

[edit] Commercial malt analyses

This section contains information on commercially available malts, derived from the malting companies' malt analysis sheets.
